I used to be a mechanical trend-follower, or actually I was into Van Tharp's expectancy risk model which made it more appropriate to grab and ride into trends. Now, I'm a little free from that and I'm able to take dips and go counter-trend in a sense.
Right now, I do both ride it and in a way counter-trend scalp. Both situations are different in which what kind of confirmation you're looking at. While I'm trading, I just see an opportunity like:
*Ping* "Hey, there's a scalping pattern...."
*Ping* "Hey, there's a trend-following pattern..."
*Ping* "Hey, there's a counter-trend pattern..."
Based on each kind of *Ping*s I'll put the appropriate stops and position size. Pings may lead to other pings like a counter-trend may lead to a trending pattern and so forth. Scalping and Counter-trend trades have extremely tight stops and trend-following pattern has a wider one.
Well, your question is: whether it's risky or not... My answer is no it's not. It's like me trying to do a brain surgery = extremely high risk and an experienced brain surgeon operating = little risk...
